Specification of Letters Patent.

Patented May 26, 1908.

Application filed November 13, 1906. Serial No. 133,247.

To all whom it may concern:

Be it known that I, HORACE L. WINSLOW, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Heating Systems, and declare the following to bea full, c1ear,' and exact de scription of the same, such as will enable others skilled in the art to which it pertains to'make and use the same, reference-being had to the accompanying drawings, which form a part of this specification.

My invention relates in general to heating systems, and more particularly to a system of uniformly distributing heated air throughout an inclosed space.

It is well'known that as hot air rises the air near the ceiling of a room is hottest, and that near the floor is coolest. It is therefore desirable that the air should circulate downwardly in order that the temperature of the room, or other inclosed space, may be uniform. It is also desirable that the air should be withdrawn from the coldest parts of the room, as for instance adjacent windows and doors, and replaced by hot air, in order that air may be at a substantially even temperature throughout the room.

The primary object of my invention is'to provide an a paratus for heating rooms, or other inclose spaces, by means of which air will be withdrawn from cold points within the room, and hot air supplied to such points to replace the withdrawn cold air, thereby uniformly distributing the hot air throughout the room.

A further object of .my inventionis to ro vide a heating apparatus bymeans of w 'cli the temperature within an inclosed space may be maintained at an even temperature throughout at a minimum cost.

A still further object of my invention is to provide a heating system which will be simplein construction, economical in operation,

and by means of which hot air may be evenly distributed throughout a room orother inclosed space. i

The embodiment of my invention herein disclosed maybe generally described as comprising a heating chamber located centrally Within the inclosed space which is to be heat ed, air supply conduits communicating with the bottom of the chamber and leading from remote points adjacent the floor of the room, a blower located within the bottom of the chamber for drawing the air from the supply conduits and forcing the same upwardly through the chamber, heat radiating 'surfaces within the chamber around which the air is forced, hot air delivery flues leading from the top of the chamber to distant points within the room, such points being 1preferably remote from the points from whic the conduits lead, whereby the hot air will be delivered at certain points and then drawn to other points from which the air has been withdrawn through the conduits.

My invention will be more fully described hereinafter with reference to the accompanying drawings in which the same is illustrated as embodied in a convenient and practical form, and in which Figure 1 is a vertical sectional view, the I top thereof being shown in elevation; Fi 2 a plan view; and Fig. 3 a cross-section ta en midway between the top and bottom of the structure shown in Fig. 1.

The same reference characters are used to designate the same parts in the several figures of the drawings.

Reference character A designates the floor of a room or other inclosed space which is to be heated.

B designates the ceiling or top Wall of the inclosed space.

While my invention is not limited in its application to any particular character of inc osed s ace, yet it is especially designed for heating arge rooms such as factories.

C designates a heater for hot air which is located within the room preferably at a central point. drical chamber which may be made of any shown-for convenience two vertical headers E and E located within the chamber and the drawings as made of brick and located beneath the floor of the room.

The heater comprises a cylin-.

I suitable material within which is located any "desired means for radiating heat. I have Reference characters D D 1) and D indicate the air sup ly conduits radiating from the heatin chamber and terminating at any points wit the room where it is desired that heat should be'drawn, as for instance adjacent windows or doors; Gratings or registers d are located in openings in the floor above the ends of the supply conduits. If desired one or more of the conduits may be providedlwith branches leading to various oints within the room, as indicated in Fig. 2 in which the conduit D is rovided with branch conduits (1", 0V, and 5 The combined capacity of the branch conduit should then e ual the capacity of the main conduit, while t e a egate capacity of the main conduits shouIrI be substantially equal to the capacity of the heating chamber C.

he inner ends ofthe supply conduits may communicate with the bottom of the heating chamber in any desired manner, as for instance by extendin through openings in the brick foundations U upon which the heating chamber is supported.

The air is drawn from the sup ly conduits and forced upwardly around the radiating surfaces within the heating chamber by means of a blower or fan F which may be suported and rotated in any suitable manner.. Ihave shown the fan F as fixed upon a vertical shaft f su ported in bearings in the brackets f an f 2 secured within the heating chamber.

F desi nates a pulley wheel secured to the lower en of the shaft f by means of which the fan may be rotated.

Flues lead from the upper end of the heating chamber to points within the room where it is desired that hot air should be de livered. Reference characters G, G G

and G designate such flues, which may be if ating surfaces wit desired provided with dampers g for regulating the discharge of hot air therethrough. The flues preferably extend from points ad- 'acent the closed upper end a of heating chamer 0 and terminate at points distant from the point from which the air supply conduits extend. i

The operation of my im roved heating system is as follows: The cold air is drawn from various points within the room adjacent the floor an passes u wardly around the radiiiin the heating. chamber,

such movement of'the'cold air to and through the heating chamber being preferably promoted by the fan F. The hot air passes from the heating chamber through the fines to the various points within the room, and from such points is drawn towards the ends of the air supply conduits to replace the air which has been withdrawn from adjacent the floor of the room.

From the above description it will be observed that by my improved heating system the temperature Within an inclosed space may be maintained evenly inasmuch as the hot air is distributed at various points within the inclosed space and circulates from such points to the points where the cold air is withdrawn. It is also evident that the uniform distribution of the heat by drawing the hot air from the u per ortion of the room toward the floor t ereo results in the desired temperature being obtained with a minimum consumption of heat.

While ,I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents, as circumstances'may sugest, or render expedient without departing om the spirit ofmy invention.

Having now fully described fny invention, what I claim as new and desire to secure by Letters Patent is:

1. In a system for heating an apartment, the combination with a heater, of a plurality of air supply conduits leading to said heater from separated points remote from the heater and adjacent thegfloor of the apartment, and a plurality of gflues for delivering hot air from said heater to se arated points within the apartment, said elivery oints being distant from said points of supp y.

2. In a system for heating an apartment, the combination with a heater, of a plurality of air supply conduits leading to'said heater from separated points remote from the heater and adjacent the floor of the apartment, a plurality of fiues for delivering hot air from said heater to separated points within the a artment, said delivery points being distant om said points of supply, and means for promoting circulation of air through said supply conduits to the heater and from the heater through said fiues.

In testimony whereof, I sign this specification in the presence of two witnesses.
